• Shut the engine (motor) off and wait until • Be alert and turn machine off if children
the blade comes to complete stop before
removing grass catcher.
• Mow only in daylight or good artificial
light.
• Do not operate the machine while under
the influence of alcohol or drugs.
• Never operate machine in wet grass.
Always be sure of your footing: keep a
firm hold on the handle and walk; never
run.
• Disengage the self-propelled mech-
anism or drive clutch on mowers so
equipped before starting the engine
(motor).
• If the equipment should start to vibrate
abnormally, stop the engine (motor) and
check immediately for the cause. Vibra-
tion is generally a warning of trouble.
• Always wear safety goggles or safety
glasses with side shields when operating

enter the area.
• Before and while walking backwards,
look behind and down for small children.
• Never allow children to operate the ma-
chine.
• Use extra care when approaching blind
corners, shrubs, trees, or other objects
that may obscure vision.
IV. SERVICE
• Use extra care in handling gasoline and
other fuels. They are flammable and
vapors are explosive.
- Use only an approved container.
- Never remove gas cap or add fuel
with the engine running.
Allow engine to cool before refueling.
Do not smoke.
- Never refuel the machine indoors.
- Never store the machine or fuel
container inside where there is an
open flame, such as a water heater.
• Never run machine inside a closed area.
• Never make adjustments or repairs with
the engine (motor) running. Disconnect
the spark plug wire, and keep the wire
away from the plug to prevent accidental
starting.
• Keep nuts and bolts, especially blade
attachment bolts, tight and keep equip-
ment in good condition.
• Never tamper with safety devices. Check
their proper operation regularly.
• Keep machine free of grass, leaves, or
other debris build-up. Clean oil or fuel
spillage. Allow machine to cool before
storing.
• Stop and inspect the equipment if you
strike an object. Repair, if necessary,
before restarting.
• Never attempt to make wheel height
adjustments while the engine (motor) is
running.
• Grass catcher components are subject
to wear, damage, and deterioration,
which could expose moving parts or
allow objects to be thrown. Frequently
check components and replace with
manufacturer’s recommended parts,
when necessary.
• Mower blades are sharp and can cut.
Wrap the blade(s) or wear gloves, and
use extra caution when servicing them.
• Do not change the engine governor set-
ting or overspeed the engine.
II. SLOPE OPERATION
Slopes are a major factor related to slip
and fall accidents which can result in
severe injury. All slopes require extra cau-
tion. If you feel uneasy on a slope, do not
mow it.
DO:
• Mow across the face of slopes: never
up and down. Exercise extreme caution
when changing direction on slopes.
• Remove obstacles such as rocks, tree
limbs, etc.
• Watch for holes, ruts, or bumps. Tall
grass can hide obstacles.
DO NOT:
• Do not trim near drop-offs, ditches or
embankments. The operator could lose
footing or balance.
• Do not trim excessively steep slopes.
• Do not mow on wet grass. Reduced foot-
ing could cause slipping.
III. CHILDREN
Tragic accidents can occur if the operator
is not alert to the presence of children.
Children are often attracted to the machine
and the mowing activity. Never assume
that children will remain where you last
saw them.
• Keep children out of the trimming area
and under the watchful care of another
responsible adult.

CONGRATULATIONS on your purchase of a new Lawn Mower. It has been designed,
engineered and manufactured to give you the best possible dependability and perfor-
mance.
Should you experience any problems you cannot easily remedy, please contact your
nearest authorized service center. They have competent, well trained technicians and
the proper tools to service or repair this unit.
• Read the SAFETY RULES and this Operator's Manual in its entirety before you at-
tempt to assemble or operate your new lawn mower to insure proper operation and to
prevent injury to yourself and others. Save this manual for future reference.
• Your new lawn mower has been assembled at the factory with the exception of those
parts left unassembled for shipping purposes. To ensure safe and proper operation
of your lawn mower, all parts and hardware you assemble must be tightened securely.
Use the correct tools as necessary to ensure proper tightness.
• All parts such as nuts, washers, bolts, etc., necessary to complete the assembly have

wear gloves or other protection when working under or lifting mower.
THINGS TO KNOW BEFOREYOU ASSEMBLE OR OPERATEYOUR LAWN
MOWER
Do I have a side or rear discharge lawn
mower?
What is the right and left side of the
lawn mower?
Look for the grass discharge opening on
your mower. If the opening is on the right
side of the mower housing, it is a side
discharge mower. If the opening is at the
back of the mower housing, it is a rear dis-
charge mower. Only rear discharge lawn
mowers have a grass catcher included with
the mower. Approved grass catchers for
side discharge mowers may be purchased
from your nearest authorized dealer.
Do I have a mulching lawn mower?
Look for the grass discharge opening on
your mower. Raise the discharge guard
(rear door on rear discharge mowers). If
the opening is closed off by a plate, then
your lawn mower is mulcher ready. To
convert to a discharging mower, see the
Operation section of this manual.
When right hand (RH) or left hand (LH) is
mentioned in this manual, it means when
you are in the operating position (standing
behind the handle).
What kind of engine is on my lawn
mower?
When learning how to operate your new
lawn mower, you will need to know what
kind of engine powers the mower. A decal
on the engine will indicate the manu-
facturer and type or brand name of the
engine.

down against handle.
• Pull starter handle quickly. Do not allow
starter rope to snap back.
BEFORE STARTING ENGINE
Read engine manual packed with your unit.
FILL ENGINE WITH OIL
Your lawn mower is shipped without oil in
the engine.
• For engines equipped with choke, slowly
move engine speed control lever to
FAST position after engine starts.
• To STOP engine, release operator pres-
ence engine control bar.
NOTE: For engines with a primer, it may be
necessary to repeat priming steps in cooler
weather. In warmer weather, overpriming
may cause flooding and engine will not start.
If you do flood engine, wait a few minutes
before attempting to start and DO NOT
repeat priming steps.
• Be sure mower is level and area around
oil fill is clean.
• Remove engine oil filler plug (oil fill cap/
dipstick on models so equipped).
• Slowly add oil. For type and grade of
oil to use, see “ENGINE” in the Mainte-
nance section of this manual.
• Fill to the top of slot in filler hole (to
“FULL” line on dipstick on models so
equipped). Do not overfill.
• Replace plug (oil fill cap/dipstick on
models so equipped) and tighten.
• Check oil level before each use. Add oil
as needed.

FILL GASOLINE TANK
MOWING TIPS
• Fill gasoline tank with fresh, clean, un-
leaded gasoline. DO NOT USE PRE-
MIUM GASOLINE. BE CAREFUL NOT
TO OVERFILL TANK.
• For most cutting conditions and better
bagging performance, the engine speed
should be set in the FAST position.
• Under certain conditions, such as when
mowing very tall grass, raise the mower
height on the first cut to reduce pushing
effort,toavoidoverheatingtheengine,and
to avoid leaving clumps of grass clippings.
Make the second cut to the desired height.
• For extremely heavy cutting, reduce the
width of cut.
• For side discharge lawn mowers, cut in a
counterclockwise direction, starting at the
outside of the area to be cut, in order to
spread grass clippings more evenly and
to put less load on the engine. To keep
clippingsoffofwalkways,flowerbeds,etc.,
make the first cuts in a clockwise direction.
• When using a rear discharge lawn
mower in moist, heavy grass, clumps
of cut grass may not enter the grass
catcher. Reduce ground speed (pushing
speed) and/or run the lawn mower over
the area a second time.
• If a trail of grass clipping is left on the right
side of a rear discharge lawn mower, mow
inaclockwisedirectionwithasmalloverlap
to collect the clippings on the next pass.
• Pores in cloth grass catchers can be-
come filled with dirt and dust with use
and the catcher will collect less grass.
To prevent this, regularly hose catcher
off with water and let dry before use.
WARNING: Experience indicates that
alcohol blended fuels (called gasohol or
using ethanol or methanol) can attract
moisture which leads to separation and
formation of acids during storage. Acidic gas
can damage the fuel system of an engine
while in storage. To avoid engine problems,
the fuel system should be emptied before
storage of 30 days or longer. Drain the fuel
tank, start the engine and let it run until fuel
lines and carburetor are empty. Use fresh
fuel next season. See Storage Instructions
for additional information. Never use engine
or carburetor cleaner products in fuel tank or
permanent damage may occur.
TO START ENGINE
CAUTION: The mower blade rotates
whenever the engine is running.
• Move engine speed control to FAST
position or to CHOKE/START position
on models equipped with choke feature.
• If your mower has a primer, to start a
cold engine, push primer the number of
times as instructed in the engine manual
packed with your mower. Use a firm
push. This step is not usually necessary
when starting an engine which has
already run for a few minutes.

TO SHARPEN BLADE
LAWN MOWER
Care should be taken to keep the blade
balanced. An unbalanced blade will cause
excessive vibration and eventual damage
to lawn mower and engine.
• The blade can be sharpened with a file
or on a grinding wheel. Do not attempt
to sharpen while on the mower.
• To check blade balance, drive a nail into
a beam or wall. Leave about one inch of
the straight nail exposed. Place center
hole of blade over the head of the nail. If
blade is balanced, it should remain in a
horizontal position. If either end of the
blade moves downward, sharpen the
heavy end until the blade is balanced.
Always observe safety rules when perform-
ing any maintenance.
TIRES
• Keep tires free of gasoline, oil, or insect
control chemicals which can harm rubber.
• Avoid stumps, stones, deep ruts, sharp
objects and other hazards that may
cause tire damage.
BLADE CARE
For best results, mower blade must be kept
sharp. Replace bent or damaged blades.
TO REPLACE BLADE
• Turn lawn mower on it’s side. See engine
manual for proper direction of turning
over the engine.
• Use a wood block between blade and
mower housing to prevent blade from
turning when removing blade bolt.
• Protect your hands with gloves and/or
wrap blade with heavy cloth.
• Remove blade bolt, lock washer and flat
washer.
• Remove blade and blade adapter.
• Inspect the key inside blade adapter.
Replace adapter if damaged.
IMPORTANT: Blade bolt is grade 8 heat
treated.
GRASS CATCHER (IF SO EQUIPPED)
Grass catcher may be hosed with water
but must be dry when used.
CAUTION: Under normal usage, the
catcher material is subject to deterioration
and wear and should therefore be checked
to ensure compliance with original
manufacturer specifi cations.
ENGINE
Read the maintenance section of your
engine manual.
• Install new or sharpened blade with
trailing edge up toward the engine.
• Position blade on blade adapter. Align
the two (2) holes in blade with raised
lugs of adapter.
• Reassemble blade bolt, lock washer
and flat washer into blade adapter and
crankshaft in exact order as shown.
• Position block of wood between blade
and mower housing.
LUBRICATION
Change the oil after the first two hours of
operation and every 25 hours thereafter or
at least once a year if the lawn mower is
not used for 25 hours in one year. Refer to
engine manual.
TO CHANGE ENGINE OIL
(SEE ENGINE MANUAL)
• Tighten blade bolt securely. Recom-
mended tightening torque is 35-40 ft. lbs.
NOTE: We do not recommend sharpening
the blade - but if you do, be sure the blade
is balanced.
• Be sure mower is on a level surface.
• Oil will drain more freely when warm.
• Catch oil in a suitable container.
• For engines without dipstick, remove
bottom oil drain plug.

AIR FILTER
CLEANING
Your engine will not run properly and may
be damaged by using a dirty air filter.
Clean the element after every 25 hours
of operation, more often if lawn mower is
used in very dusty, dirty conditions.
See the maintenance section of your
engine manual.
IMPORTANT: For best performance, keep
mower housing free of grass build-up and
trash. Clean the underside of your mower
after each use.
• Clean the underside of your lawn mower
by scraping to remove buildup of grass
and trash.
• Clean engine often to keep trash from
accumulating. A clogged engine runs
hotter and shortens engine life.
• Keep finished surfaces and wheels free
of all gasoline, oil, etc.
We do not recommend using a garden
hose to clean your lawn mower unless the
electrical system, muffler, air filter, and
carburetor are covered to keep water out.
Water in engine can shorten engine life.
SPARK PLUG
Change the spark plug once a year to
make the engine run better and easier
to start. Set spark plug gap according to
engine manual specifications.
MUFFLER
Inspect and replace corroded muffler as it
could create a fire hazard and/or damage.
SERVICE AND ADJUSTMENTS
• The air filter must be assembled to the
carburetor when running engine.
• Best carburetor adjustment is obtained
when fuel tank is 1/4 full.
• In order for the engine to run, the opera-
tor presence control bar must be held
in the operating position. Therefore,
and assistant will be required to hold
the control bar in the operating position
when making final adjustment to the
carburetor.
CAUTION: Before performing any
service or adjustments-
• Release operator presence control bar.
• Make sure the blade and all moving
parts have completely stopped.
• Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with spark plug.
LAWN MOWER
REAR DEFLECTOR (IF EQUIPPED)
See the adjustment section of your engine
manual for further instructions.
The rear deflector, attached between the
rear wheels of your mower, is provided to
minimize the possibility that objects will
be thrown out of the rear of the mower
into the operator mowing position. If the
deflector becomes damaged, it should be
replaced.
ENGINE SPEED
The engine speed has been factory set.
Do not attempt to increase engine speed
as it may result in personal injury. If you
believe the engine is running too fast
or too slow, take your lawn mower to an
authorized engine service center for repair
and adjustment.
ENGINE
CARBURETOR
The carburetor has been preset at the fac-
tory and adjustment should not be neces-
sary. However, minor adjustment may be
required to compensate for differences in
fuel, temperature, altitude or load.
THROTTLE CONTROL
If it becomes necessary to adjust or
replace the throttle control, see the adjust-
ment section of your engine manual.

STORAGE
Immediately prepare your lawn mower for
ENGINE
storage at the end of the season or if the
unit will not be used for 30 days or more.
CAUTION: Never store the lawn mower
with gasoline in the tank inside a building
where fumes may reach an open flame
or spark. Allow the engine to cool before
storing in any enclosure.
FUEL SYSTEM
IMPORTANT: It is important to prevent
gum deposits from forming in essential fuel
system parts such as carburetor, fuel filter,
fuel hose, or tank during storage. Also,
experience indicates that alcohol blended
fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads
to separation and formation of acids during
storage. Acidic gas can damage the fuel
systme of an engine while in storage.
LAWN MOWER
When lawn mower is to be stored for a pe-
riod of time, clean it thoroughly, remove all
dirt, grease, leaves, etc. Store in a clean,
dry area.
• Cleanentirelawnmower(See“CLEANING”
intheMaintenancesectionofthismanual).
• Lubricate as shown in the Maintenance
section of this manual.
• Be sure that all nuts, bolts, screws, and
pins are securely fastened. Inspect
moving parts for damage, breakage and
wear. Replace if necessary.
• Touch up all rusted or chipped paint
surfaces; sand lightly before painting.
• Drain the fuel tank.
• Start the engine and let it run until the
fuel lines and carburetor are empty.
• Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.
• Use fresh fuel next season.
NOTE: Fuel stabilizer is an acceptable
alternative in minimizing the formation
of fuel gum deposits during storage.
Add stabilizer to gasoline in fuel tank or
storage container. Always follow the mix
ratio found on stabilizer container. Run
engine at least 10 minutes after adding
stabilizer to allow the stabilizer to reach the
carburetor. Do not drain the gas tank and
carburetor if using fuel stabilizer.
HANDLE STORAGE
(HANDLE BRACKET MODELS ONLY)
Your handle may be folded for storage as
shown.
• Squeeze the bottom ends of lower
handle towards each other until handle
clears the handle brackets and swing
handles forward over mower.
• Loosen upper handle mounting hard-
ware enough to allow upper handle to be
folded back.
ENGINE OIL
Drain oil (with engine warm) and replace
with clean oil. (See “ENGINE” in the
Maintenance section of this manual).
IMPORTANT: When folding handles for
storage or transportation, be sure to fold
handles as shown or you may damage the
control cables.
CYLINDER
• Remove spark plug.
• Pour one ounce (29 ml) of oil through
spark plug hole into cylinder.
When setting you handles up from the
storage position, the lower handle will au-
tomatically lock into mowing position.
• Pull starter handle slowly to distribute oil.
• Replace with new spark plug.
OTHER
• Do not store gasoline from one season
to another.
• Replace your gasoline can if your can
starts to rust. Rust and/or dirt in your
gasoline will cause problems.
• If possible, store your unit indoors and
cover it to protect it from dust and dirt.
• Cover your unit with a suitable protective
cover that does not retain moisture. Do
not use plastic. Plastic cannot breathe,
